Do you need a special version of the graphics card for it to work in the G5? Couldn't you just dump in any old card and see what happens? Shouldn't it work even in a basic mode which would allow testing to happen ???


Every computer needs a "special" video card that has firmware that interacts with the firmware on the mainboard to be able to display anything prior to the OS taking over. Intel based PCs from most manufacturers use a video card capable of talking to the BIOS, newer machines like Apples Intel Macs have video cards capable of talking to EFI, PowerPC Macs have firmware capable of talking to Open Firmware, and so on. Some video cards have the capability of working with multiple systems, but for now they are rare. I think newer video cards are mostly shipping with both EFI and BIOS compatibility, but the thing that then hampers you from putting an EFI card into a newer Intel Mac is lack of OS drivers.
